DLNiG- SYSTEM FR VEHICLE SPRNGS.

Application filed October 15, 1920. Serial No. 417,076'.

lie known that l, lul rriN Orsini, a citiot i United platesa and a resident of "eff :a lily' invention relates to new and useful improvements in oilii g systenis to? vehicle springs, and has for its principal objeet the provision oit a new and improved construeg tion and arrangement et parte by which an improved oi ing edeet shall be attained assuringa complete lubrication of all engaging' parts.

@ther objeets will appear hereinafterv The invention Consists in the combinations and arrangements oi parts hereinatter described and claimed.

The invention will be 'best understood by reference to the accompanying; drawings forming a part of this speciiieation, and in which,

Fig. l, is a side view of one form et' my improved construction,

vpoint for lubrication.

An opening` Q0 is also provided through the learrv7 in position to communicate at its upper end with the longitudinally extending` groove 19, as is shown in Fig. l. By the provision of the grooves 19, the oil which is deposited upon the upper t'aee ot the spring near its outer end, adapted to be direeted alongg` the spring; so as to be carried to the desired 'l1 he openingr 20 through each of the leaves is so positioned as to communicate, at its lower vend, with the Groove 19 formed in the upper tace of the leaf next below, whereby the oil delivered to the upper face of the uppermost intermediate leaiz is distributed by means of the grooves 19 and the opening- 20 to the upper faces of all of the several leaves of the spring.

The means for delivering the oil to the end portion oit the upper face of the uppermost intermediate leaf, as such oil delivering means is constructed, as shown at the right-hand end portion ot Fig. l, comprises a bolt 2l mounted in the eye 18, a brass bushing 22 being interposed between the bolt and the eye 18. The bolt 2l is provided with a central opening 23 at one end, which is turned at an angle at about the middle portion of the bolt, so as to communicate with openings 9A and 25 through the bushingv 22, and the uppermost leal l5 of the spring, re speetivelyl0 the lower end ot the opening 25 being directly above the groove i9 oit the up- }')ermost intermediate leaic l5. A. hollow stem 26 is mounted, by means of screw threads, in the head ot the bolt 2l so as to communioate with the opening 23, an oil cup 27, of any approved type, being` mounted upon the outer turned up end of the stein Q6.

The construction at the opposite end of the spring' is slightly different. At this point a hollow stem 28 is tapped directly into the lower vtace o' the uppernmst intermediate lea't l5, the stem 25% bei ng coi'ineeted at its outer end with an oil cup 29 which is held in elevated position so as to secure a delivery ot' oil upwardly through the end of the stem 28 to the upper 'face of the leaf upon which it is mounted`r the stem being mounted in such position as to deliver the oil to the groove i9 in such leaf.

l/Vhile l have illustrated and described the preferred form of construetion for carrying my invention into eiteet, this is capable of variation and modification without departing from the spirit of the invention. L

therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modications as come Within the scope of the appended claims.

Having described iny invention, What I claim as new and desire to secure by Letters Patent is :-A

l. A spring comprising a plurality of superposed leaves; a holloii7 stein tapped upwardly through the end portion of the uppermost intermediate leaf; and an oil cup connected with said stem in position for delivering oil b gravity upwardly through the stein, said leaf being provided with a plurality of longitudinally extending groove portions in its upperlace at the point Where the oil' is deposited from said oil cup for directing the oil along the leaf to the desired point for lubrication, substantially as described.

2. A spring comprising a plurality of superposed leaves; a curved hollow stem tapped through the end portion of the uppermost intermediate leaf; and an oil'cup connected with said stem and mounted above the same in position for delivering` oil up wardly through the stem, each of said intermediate leaves being provided With a longitudinally extending groove and two groove portions parallel thereto and connected therewith by means of a lateral groove por tion in the upper face of the leaf at the point Where the oil is delivered thereto for directing the oil along the leaf tothe desired place for lubrication, substantially as described.

In testimony Whereot l have signed my name to this specification in the presence of two subscribing Witnesses.
